Title: Tetrahedral forging device
Inventor: NAKAJIMA MASAO
IPC: B21J7/14
Filed: 1988-04-04
Abstract: PURPOSE:To prevent the surface temperature of a stock to be forged from falling and to obtain a forged part free from cracks and excellent in quality by providing respective burners on both sides of a position pressed centripetally by an anvil. CONSTITUTION:A cylindrical stock to be forged taken out of a heating furnace is rotated intermittently and introduced from the introducing side of a forging device. In this case, since the burners are arranged on both sides of the position pressed centripetally by the anvil, the surface temperature of the stock to be forged is prevented from being lowered by the braze from burner nozzles 51, 52 on the introducing side. The stock to be forged is forged by the anvils 31-34 set to hammers 21-24 moving at the same time in the direction rectangular to the axial direction and transmitted to a transmitter side. Since the stock to be forged which is transmitted to the transmitter side undergoes an operation opposite to the above-mentioned operation as occasion demands and is exposed to the blaze from the burner nozzles 53, 54 of the transmitter side, the reduction of the surface temperature is weakened. Accordingly, it is possible to obtain a forged part free from surface cracks and excellent in quality.

Title: Partial chemical plating method
Inventor: YAMADA SHIYOUGO
IPC: C23C18/31
Filed: 1978-07-05
Abstract: PURPOSE: To apply plating for arbitrary patterns such as of brush-written characters on water absorptive material surface by sensitizing only the surface requiring plating then covering the entire surface including the surface requiring plating with a protection film composed of an extra thin layer of hydrophobic material.  
     CONSTITUTION: An Indian ink stick is rubbed down with, e.g., an aqueous solution of SnCl 2  to prepare an Indian ink for sensitizing. This is used to write characters on paper surface with a writing brush. After drying, the surface is waterproofed with a commercial waterproof spray, thence this paper is dipped in a palladium chloride solution. Since the paper itself is waterproofed, there is no penetration of the liquid and the paper retains the original form but metal Pd deposits in the character surfaces through the waterproof layer, thereby forming active nuclei. After a suitable time, the paper is taken out from the solution, is rinsed, and is then dipped in a plating solution to apply the specified amount of plating on the character surface. This invention is characterized by sensitizing the specific portions of the hydrophilic surface then covering the entire surface with the extra thin film of hydrophobic synthetic resin in the above mentioned manner.
